This is the third coat of this model that I have purchased for my son, going up a size each year. I’ve been very happy with the durability of this coat. This last coat, however had a faulty zipper which detached the first time my son wore the coat. Thankfully, MW replaced the coat. Hopefully the zipper on this new one does not detach so easily.

Perfect jacket for in-between weather. Fits a little smaller than I thought it would for a size 9-10. Grandson is a slim 8-year-old and it just fits him, but it will be fine. The main thing is he loves it.

Bought as a Christmas present for my grandson, so not been worn yet. However, I read the reviews and I'm sure he will like it. His mum does. Very pleased with the delivery time. All in all, good coat, good price and good service. Im very happy with my purchase.

Very practical, excellent quality, great buy.
3 in1 Coat was very nice but a bit on the small size for 7-8 years. Next size up was 9-10. I don’t usually have any problem with other clothing in that size. So will have to return to store.
Great coat for all round use
It’s on the small side. If you’re buying this you’ll probably need several sizes bigger! Can’t comment on the quality cause my child can’t fit in it.
